data

Effect of epoxy level on appearance

Format

A data frame with 10 observations on the following 2 variables.

• epoxy: level of epoxy in formulation
• lw: longwave measure of appearance

Details

Long wave is a measurement used to characterize a surface, such as the paint on an auto. In this instance higher LW was desired and the amount epoxy was one component of the paint that was known to impact the LW properties of the final product.
